Exporting animated materials to Unity
Reference: https://forum.unity.com/threads/can-blender-2-8-eevee-shaders-still-be-used-with-unity.645271/

Asking a Unity3D game developer about your question brought me to the conclusion that you can't actually export "animated materials" from Blender to Unity unless you recreate the shader IN Unity/ More info in the link i gave you.
